Description

  The present invention relates to a vehicle display system that performs image display on a plurality of displays using a graphic display control unit (also referred to as GDC).

  Conventionally, some navigation devices have two displays and display different images, and GDC is required for each of the two displays. Thus, a two-screen display output system described in Patent Document 1 has been proposed. In Patent Document 1, a storage unit that temporarily stores image information output from a single GDC, a frequency dividing unit that divides a reference clock by a half frequency, and a portion that relates to a display at a frequency divided A first reading unit that reads the first image information, and a first output unit that outputs the first image information together with the synchronization signal.

  Further, a second reading unit that reads the second image information of the portion related to the display at a frequency division frequency delayed from the first reading unit, a delay unit that delays the synchronization signal output from the GDC, and a second A distributor having a frequency dividing frequency and a second output unit that outputs the image information together with a synchronization signal delayed by a predetermined time by the delay unit is provided. This distributor distributes common image information written by the CPU to the GDC to a plurality of displays in a hardware manner (mechanically) regardless of the control of the CPU.

  FIG. 11 is a block diagram of a vehicle display system 100 used in a current automobile. As shown in FIG. 11, a meter display 4 for displaying the vehicle speed and alarms with an instrument and an alarm in the instrument panel, a head-up display 5 for projecting the vehicle speed and the like onto the windshield in front of the driver's seat, and navigation such as a map displayed in the center of the vehicle A navigation display 6 for displaying information and the like is provided.

  The meter display 4, the head-up display 5, and the navigation display 6 are provided with dedicated GDCs 1A, 1B, and 1C and CPUs 2A, 2B, and 2C that form a control unit, respectively. In addition, there was a one-chip CPU and GDC. Further, the CPUs are connected by a multiplex communication line (in-vehicle LAN) 50 that employs a protocol such as CAN.

JP 2010-169753 A

  In such a conventional vehicle display system, if Patent Document 1 is applied, the navigation display 6 is substantially separated into two display units as indicated by a broken line Y11, and a map is displayed on one display unit and the other display is displayed. A night vision image or the like can be displayed on the screen. In this case, the image information is transmitted from the distributor built in the GDC 1C to each display unit constituting the navigation display 6 as indicated by a broken line.

  On the other hand, the inventor considered displaying a movable image that is an image portion straddling the meter display 4, the head-up display 5, and the navigation display 6. This movable image is an image that moves across displays between different display devices, for example, between the navigation display 6 and the meter display 4, as shown in FIG.

  In this case, for example, it is easy to copy the vehicle graphic symbol 51 displayed on the meter display 4 and paste it as the graphic symbol 52 in the navigation display 6, but the graphic symbol 51 displayed on the meter display 4. It is relatively difficult to display the movement state sequentially so that the vehicle can run in the direction of the navigation display 6, that is, to display the movable image.

  In order to display this movable image, it is necessary for the CPUs 2B and 2C in FIG. 11 to execute an instruction for alternately writing the movable images to be displayed to the one and the other GDCs 1B and 1C. The display 4 and 6 are difficult to synchronize with each other, and the performance is reduced accordingly. Furthermore, the amount of information exchange in the multiplex communication line 50 such as CAN that communicates between the GDCs 1B and 1C increases, and smooth image display is difficult.

  Specifically, as shown in FIG. 13, when the graphic symbols 51 and 52 are displayed across the display 6 from the end of the display 6, the GDC 2 </ b> C of the one display 6 is connected to the vehicle via the multiplex communication line 50. It is necessary to inform the GDC 1B of the other display 4 where the last position is. Accordingly, the GDC 1B of the other display 46 has to display the graphic symbols 51 and 52 by calculating the position of the head of the vehicle by interpolation calculation.

  Moreover, communication related to the synchronization data must be executed sequentially and in real time via the multiplex communication line 50, and the exchange of the synchronization data is complicated, the amount of information becomes enormous, and the communication time It also takes. Further, it is necessary to store the image creation data related to the design GS1 and GS2 of the same graphic symbol in the RAM or the like in both GDC1B and GDC2C.

  The present invention has been made paying attention to such problems existing in the prior art, and its purpose is to display a movable image that moves across displays of different display devices. An object of the present invention is to provide a vehicle display system that can display a movable image that moves smoothly at high speed between different displays, without the need for complicated transmission and reception of synchronization data between the displays.

  In order to achieve the above object, the present invention employs the following technical means. That is, according to the first aspect of the present invention, there is provided a vehicle display system including a first display and a second display for displaying different vehicle information as first and second information images, and the first and second displays adjacent to each other.

  According to the present invention, in order to display a movable image that moves between the first display and the second display, the graphic display control unit includes a plurality of units corresponding to the first display and the second display. It is only necessary to generate image information that can be divided into pixel areas, and there is no need to provide a plurality of graphic display control units corresponding to the respective displays. Furthermore, since the image information is only distributed by the distribution unit for each pixel area, there is no need for complicated transmission and reception of synchronization data between the first display and the second display, and the high-speed and smooth image portions are different. Can be displayed between displays.

  According to a second aspect of the present invention, the first generation unit that generates the first information image, the second generation unit that generates the second information image, and the movable image generation unit that generates the movable image It is characterized by composing means for generating a composite image.

  According to the present invention, since the first generation unit and the second generation unit may be configured by different software to form a common movable image generation unit, different technologies such as a meter and navigation are used. The graphic display control unit can be configured by bringing software created separately for each field.

  According to a third aspect of the present invention, a control unit for controlling the graphic display control unit is further provided. In the control unit, a destination of the movable image is designated based on an operation of an occupant of the vehicle. It is characterized by including the designation means to do.

  According to this invention, based on the operation of the vehicle occupant, the movable image can be moved and displayed on an arbitrary display, and a novel image in which the displays are linked can be provided.

  According to a fourth aspect of the present invention, the first display is a front seat display arranged around the front seat of the vehicle, and the second display is arranged around the rear seat of the vehicle. It is a seat display.

  According to the present invention, an image including a movable image moving between the displays between the front seat display arranged in the front seat of the vehicle and the rear seat display arranged in the rear seat of the vehicle. Can be displayed, so that an unprecedented novel image can be provided.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a block configuration diagram of a vehicle display system showing a first embodiment of the present invention. A vehicle display system 100 shown in FIG. 1 mainly includes a computer control unit (also referred to as CPU) 1 constituting a control unit, a graphic display controller (also referred to as GDC) 2 constituting a graphic display control unit, and a distribution unit. It comprises a distributor 3, a meter display 4 that is a display of a meter display device, a head-up display 5 that constitutes a display for other devices, and a navigation display 6.

  The meter display 4 (also referred to as a first display) is a display that is provided in the instrument panel 10 of the vehicle and has a meter display unit that displays information including the speed of the vehicle. The head-up display 5 is a display of a head-up display device that projects and displays information including the vehicle speed on one corner of the windshield 11 of the vehicle.

  FIG. 2 is a front view showing details of the meter display 4. The meter display 4 is entirely formed by a single liquid crystal panel using TFT liquid crystal, and a known touch sensor is provided so that the liquid crystal panel can be operated by touching the finger of the driver. In FIG. 2, the meter display 4 includes a speedometer 12, a tachometer 13, and a travel distance accumulator (travel distance display unit) 14. The speedometer 12 instructs the vehicle speed of the passenger car using the scale plate 12a and the pointer 12b. Similarly, the tachometer 13 instructs the vehicle speed of the passenger car using the scale plate 13a and the pointer 13b.

  The mileage accumulator 14 digitally displays an accumulated distance that is an accumulated value of the mileage of the vehicle, and can display values from 0 km to 999,999 km. The meter display 4 has a warning display unit 16 for displaying various warning information in the car with pictographs. The various warning information displayed in the warning display unit 16 includes, for example, door opening or half-door information, on / off information of the transmission overdrive stage, battery charge state, remaining fuel shortage state, headlamp remote lighting state, engine oil Items such as quantity reduction information that should be warned can be displayed in color or lit.

  A navigation display (also referred to as a second display) 6 in FIG. 1 is a display of a navigation display device that displays map information indicating the traveling position of the vehicle, and is provided on a center console of the vehicle (not shown). The GDC 2 in FIG. 1 generates image information to be displayed on the meter display 4, the head-up display 5, and the navigation display 6 as integrated image information.

  The distributor 3 serving as a distribution unit distributes the image information generated by the GDC 2 to the meter display 4, the head-up display 5, and the navigation display 6 for each pixel area. The CPU 1 is a control unit unit that performs overall control of the operation of the vehicle display system 100. The GDC 2 is connected to a ROM 21 and a RAM 22 that store and store a program and data for creating an image to be displayed on each display 4, 5, 6. Further, the GDC 2 outputs image information including color data (hereinafter also referred to as pixel data) RGB displayed on each of the three displays 4, 5, 6 to the distributor 3 as shown in FIG. 1.

  FIG. 3 is a block configuration diagram showing an internal configuration of the distributor 3. As shown in FIG. 3, the GDC 2 generates a horizontal synchronizing signal Hsync, a vertical synchronizing signal Vsync, and a reference clock signal clock serving as a reference for transferring pixel data to synchronize the display of the three displays 4, 5, and 6. And output.

  The distributor 3 is between the GDC 2, the meter display 4, the head-up display 5, and the navigation display 6. Pixel data RGB that are image information obtained by combining image creation data input from the RAM 21 in FIG. It is a part which distributes so that it may be displayed on the display 4,5,6.

  In FIG. 2, for example, a door opening or half-door information image 16 a displayed on the warning display unit 16 in the meter display 4 has a small image and it is difficult to know which door is open. Therefore, if the door opening or half-door information image 16a is dragged with the finger to the lower left as indicated by the arrow Y2 and can be displayed on the navigation display 6 as shown in FIG. The arrow Y4 in FIG. 4 is not displayed. It indicates the direction in which it feels that it has flew (moved).

  In this case, it is preferable to display not the simple copy-and-paste but the above-described straddling image portion so that an image in which the image portion (movable image) is jumped from the meter display 4 to the navigation display 6 can be displayed. Such a display form is also desired to be performed between the meter display 4 and the head-up display 5.

  As described above, in order to display that the image portion has flew, in the first embodiment, the movable image moves from the meter display 4 toward the navigation display 6, and the door is displayed on the navigation display 6 after this movement. The open or half-door information image is enlarged and displayed. For this purpose, it is necessary to display the movable image across the movable display from the meter display 4 to the navigation display 6.

  FIG. 5 is an explanatory diagram for schematically explaining the movable image in the first embodiment. In FIG. 5, for example, a state in which an image portion of an automobile viewed from an oblique front is moving from the meter display 4 to the navigation display 6 in the direction of the arrow Y5 is schematically illustrated. In the following description, it is assumed that the movable image is an automobile as shown in FIG.

  In the first embodiment, an image portion (movable image) straddling between two screens in the same image display device is not generated, but is originally displayed like the meter display 4, the head-up display 5, and the navigation display 6. The content is different and the movable image is not normally generated between the displays of different image display devices. The movable image is actively displayed, and when viewed from the driver, the whole cockpit is interlocked. is there.

  For this purpose, as shown in FIG. 1, in a vehicle display system comprising a set of three different display devices (head-up display device, meter display device, navigation device), using a single GDC 2 controlled by the CPU 1, The image information generated by the single GDC 2 is distributed by a distributor 3 that constitutes a distribution unit for each pixel area described later.

  In FIG. 3, first, pixel data RGB to be displayed on a virtual single display is input to the distributor 3 together with the reference clock clock from the GDC 2 in FIG. 1. In other words, the GDC 2 outputs pixel data RGB as image information with the intention of displaying an image on a single virtual display.

  FIG. 6 is a schematic diagram showing a virtual single display for schematically explaining image information output by the GDC 2 in the first embodiment. In FIG. 6, the GDC 2 can display an image on a single virtual display 30 indicated by a broken-line frame. In other words, when the image information output from the GDC 2 is displayed on an actual single display, an image as shown in FIG. 6 can be displayed.

  In this virtual display 30, a graphic symbol 31 made up of a movable image shown in a perspective view of the vehicle is moved from right to left. In the single virtual display 30, four pixel areas (virtual display areas) are set according to the pixel positions on the display 30.

  The four pixel areas include a non-display pixel area 32 that displays nothing, a HUD pixel area 33 that displays an image related to the head-up display device, a meter pixel area 34 that displays an image related to the meter display device, and navigation. It is divided into a navigation pixel area 35 for displaying an image related to the display device.

  FIG. 7 is a flowchart showing processing in the CPU 1 (FIG. 1) that issues a command to the GDC 2 to control the GDC 2. The processing in the CPU 1 is executed by a program stored in the ROM 21. In FIG. 7, when the image moving process is started, the image creation data of the graphic symbol 31 of FIG. 6 is read from the RAM 22 in step S1.

  Next, in step S2, the image display position of the image portion of the graphic symbol 31 (FIG. 6) is designated in GDC2, and the image portion is displayed at that position in step S3. As a result, a movable image of the graphic symbol 31 composed of a perspective view of the vehicle is displayed in the meter pixel area 34 which is the initial image display position in FIG. This display of the movable image is displayed as a composite image superimposed on a background image composed of a meter display image. That is, a background image composed of a meter display image is generated by first generation means (software) that generates a first information image, and is synthesized by the movable image generation means that generates a movable image and the first generation means. The image is composed.

  Next, in step S4 of FIG. 7 that constitutes a designation unit that designates the destination of the movable image, the position of the destination of the movable image is designated based on the operation (such as a drag operation) of the passenger in the vehicle. Next, in step S5, an image in which the movable image is moving from the initial image display position to the designated movement position is generated. For this purpose, a plurality of images in which the graphic symbol movable image moves for each pixel are generated. The plurality of generated images are stored in the RAM 22. At this time, when the shape of the image gradually changes, a moving image may be generated using morphing, which is one of computer graphics techniques.

  Next, in step S6. By sequentially extracting the image information stored in the RAM 22 and outputting it as image information, the movable image of the graphic symbol 31 is designated as shown in FIGS. 6 (a) to 6 (b). The display can be performed so as to move to a position in the navigation pixel area 35.

  The display of the movable image in the navigation pixel area 35 is also superimposed on the background image made up of the navigation display image as a composite image. That is, a background image composed of navigation display images is generated by second generation means (software) that generates a second information image, and is synthesized by the movable image generation means that generates a movable image and the second generation means. The image is composed. Such generation of image information can be easily performed by the GDC 2.

  The vehicle speed display displayed in the HUD pixel area 33 in FIG. 6 can be changed in real time according to the vehicle speed even while the image portion of the graphic symbol 31 moves to the designated movement position. FIG. 6 illustrates a case where the vehicle speed has not changed during this period.

  As described above, the graphic symbol 31 can be easily moved from right to left in an image that can be displayed on the single virtual display 30. Similarly, a movable image composed of a specific image portion such as the “door open or half-door information image” described with reference to FIGS. 2 and 3 can be displayed on the single virtual display 30. In 30, it is possible to easily move the specific image portion from right to left.

  That is, in a single virtual display 30, a specific image portion or graphic symbol such as a door opening or half-door information image 16a is moved from right to left, and the navigation pixel from within the meter pixel area 34 of FIG. It is easy to move sequentially into the region 35.

  In reality, there is no single virtual display 30, and as shown in FIG. 1, the image information of the GDC 2 is input to the distributor 3 constituting the distributor. The distributor 3 shown in the block diagram of FIG. 3 converts the image information as shown in FIG. 6 that can be displayed on the single virtual display 30 by the GDC 2 into pixel regions (virtual regions) partitioned on the single virtual display. Display area) 33, 34, and 35 are distributed and displayed on displays 4, 5, and 6 of different display devices.

  Of course, the image information created by the GDC 2 is displayed on an actual single display (for example, a rear seat display), and the image displayed on the actual single display is divided into pixels divided on the single display. You may make it display on the display 4,5,6 of a different display apparatus for every area | region 33,34,35.

  The distributor 40 in FIG. 3 mainly receives an image memory 40 to which pixel data RGB in the image information generated by the GDC 2 is input, and a synchronization signal composed of a reference clock signal clock, a horizontal synchronization signal Hsync, and a vertical synchronization signal Vsync. An input memory control 41 includes a synchronization control 42 which receives the synchronization signal and supplies the synchronization signal to the displays 4, 5 and 6 of different display devices.

  The memory control 41 displays the image information in the image memory 40 on each display for each of the non-display pixel area 32, the HUD pixel area 33, the meter pixel area 34, and the navigation pixel area 35 in FIG. Specifically, the image information that can be displayed on the virtual display 30 in FIG. 6 written by the read command from the memory control 41 is the image information that can be displayed on the virtual display 30 based on the write command from the memory control 41. Is output as a color signal common to the respective displays 4, 5, 6 while scanning in the horizontal direction.

  The synchronization signal from the synchronization control is sent to the head-up display 5 when the image information that can be displayed on the virtual display 30 is scanned in the horizontal direction, when the position corresponding to the pixel region 33 is first scanned. Display is possible only with the head-up display by the given synchronization signal. In this way, when the scanning line moves in the vertical direction while scanning in the horizontal direction, the scanning of the pixel region 33 is completed, and then the pixel regions 35 and 34 are scanned. When the scanning line is scanning over the pixel area 35, the synchronization signal enables display of pixel information only on the navigation display 6. Further, when the scanning line is scanning over the pixel region 34, the synchronization signal enables display of pixel information only on the meter display 4. In this way, the image information of the respective pixel areas 33, 34, and 35 is displayed on the head-up display 5, the meter display 4, and the navigation display 6.

  As described above, according to the vehicle display system 100 of the first embodiment, the image information of the three pixel regions 33, 34, and 35 generated by the GDC 2 is distributed to the displays 3, 4, and 5 by the distributor 40. Since each pixel area 33, 34, 35 is appropriately distributed, one GDC 2 can perform display control of three screens. The functional circuit of the distributor 3 can also be configured with the GDC 2 and one chip.

  Further, according to the vehicle display system 100 of the first embodiment, the GDC 2 that forms the graphic display control unit is controlled by the CPU 1 that forms the control unit unit to generate image information that can be displayed on a single virtual display. Well, the load on the CPU 1 can be reduced. In addition, since it is not necessary to arrange the GDC 2 by the number of displays 3, 4, and 5, the configuration is easy.

  Furthermore, since it is not necessary to generate a movable image composed of straddling image parts in the GDC 2 while coordinating via a multiplex communication line (in-vehicle LAN), it is only distributed by the distributor 2, so that a high-speed and smooth straddling image is obtained. The part can be displayed between different display devices.

  Thus, a movable image can be smoothly displayed at high speed between the meter display device, the head-up display device, and the navigation display device. Therefore, when viewed from the driver, the entire cockpit becomes a display image that is linked, and a vehicle display system that can provide a very innovative display image can be obtained.

  Next, in the case where the first display is a meter display that displays information including at least the vehicle speed in the instrument panel of the vehicle, and the second display is a navigation display that displays map information indicating the traveling position of the vehicle, The image portion that moves across the pixel areas is composed of an image portion related to the information image in the warning display portion displayed on the first display, and this image portion is enlarged and displayed in the navigation display.

  According to this, since the image portion related to the information image in the warning display portion displayed on the meter display is moved and enlarged across the navigation display, it is easy to understand that the display content has moved, By doing so, it is possible to make the display content easier to see.

  Furthermore, the movement between the first display and the second display of the movable image that moves across the pixel areas is triggered by the drag operation of the touch switch on the first display. According to this, it is possible to easily instruct to move the movable image by dragging on the first display.

  Further, the image information composed of the composite image generated by the GDC is output while scanning as pixel information common to the displays 4, 5, and 6, and the position corresponding to the pixel region 33 (first pixel region) is scanned. The pixel information can be displayed only on the head-up display (first display) by the synchronization signal given to the head-up display 5 (first display), and the scanning of the pixel area 33 (first pixel area) is completed. Then, when scanning is performed on the pixel area 35 (second pixel area), the synchronization signal enables the pixel information to be displayed only on the navigation display 6 (second display).

  In this way, the image information of each pixel region 33, 34, 35 is displayed on each display (head-up display 5, meter display 4, navigation display 6) as it is scanned. According to this, pixel information can be easily distributed even when there are a large number of pixel areas and displays.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. In the following embodiments, the same components as those in the first embodiment described above are denoted by the same reference numerals, description thereof will be omitted, and different configurations and features will be described. FIG. 8 is a block diagram of a vehicle display system showing a second embodiment of the present invention. In FIG. 8, a rear display 7 is also provided around the rear seat, and a television screen or the like can be viewed on the rear display.

  For example, when the driver wants to show a map to the passenger in the rear seat, the driver performs an operation of rubbing the surface of the navigation display 6 around the front seat from the top to the bottom, thereby detecting the drag operation of the passenger by the touch sensor, and navigation. A small image is copied, and a thumbnail image composed of the small copied map image moves from the upper side to the lower side on the navigation display 6 and moves to the rear display 7 of the rear seat.

  Further, a movable image made up of thumbnail images falling from above on the rear display 7 is located at the center, and is enlarged so that a map image is developed on the rear display 7. Such an image display for the rear display 7 can be easily generated as image information that can be displayed by the single GDC 2 in the non-display pixel region 32 of FIG.

(Third embodiment)
Next, a third embodiment of the present invention will be described. Features different from the above-described embodiment will be described. FIG. 9 is a front view showing details of a meter display showing a third embodiment of the present invention. In the third embodiment, in order to indicate to the driver a state in which the image portion is skipped to another display, a movable image composed of arrows is skipped between the displays.

  In FIG. 9, when the door opening or half-door information image 16a is dragged to the lower left, an arrow Y9 is displayed. This arrow Y9 becomes longer and larger, and the tip moves downward. Finally, as shown in FIG. 10 (a), the tip of the arrow Y10 moves into the navigation display 6, and the arrow Y10 is deformed to open the moved door or as shown in FIG. 10 (b). The half-door information image 16ab is displayed in the navigation display 6, and which door is open is enlarged and displayed.

(Other embodiments)
The present invention is not limited to the above-described embodiments, and can be modified or expanded as follows. For example, in the first embodiment described above, a graphic symbol in the shape of a vehicle or an arrow has moved across, but this movable image can be displayed by moving a graphic symbol representing a wavy wave or a bubble graphic. Any graphic symbol is possible, such as moving a symbol. Further, movement between arbitrary displays such as movement from the meter display 4 to the head-up display 5 is possible.

  Next, the ripple generated on the meter display 4 may spread toward the head-up display 5 to prompt the driver to see the head-up display. In this case, it is not necessary to move substantial vehicle information such as a partial display of the warning display unit 16 in the meter display 4 to the head-up display. For example, it consists only of graphic symbols such as arrows, ripples and bubbles. It may be simply moved across the movable image.

  A movable image straddling a plurality of displays is not only moving the image part as shown in FIG. 4, but is also reduced or enlarged at the destination of the image part, and the fade-in is changed from a single color state to a state where the image part is gradually visible. (Fade-in), it is more effective when implemented in combination with other moving image playback techniques such as fade-out, which gradually changes from a visible state to a single color.
